FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 694,629, dated March 4,1902.

Application filed May 22, 1901.

To all whom it may concern.-

companying drawings, and to the letters of reference marked thereon,which form a part of this specification.

My invention has relation to flushing-valves and valve-controllingmechanism for flushingtanks, and has for its object the provision ofnovel mechanism whereby when the tank is full and the valve raised toopen the flush-pipe outlet the valve-stem will frictionally engage witha suitable lever and be firmly held in an elevated position until thetank is completely emptied and the lever raised by the descent of thefloat and the operation thereby of a trip-lever which will release thevalve-stemand allow the valve to drop and close the flushpipe. 7

My invention consists in the novel construction and combination of partshereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure 1 is a longitudinal section of aflushing-tank and its connections embodying my invention. Fig. 2 is aplan view of the valve. and valve-controlling mechanism. Fig. 3 is atransverse section on the line X X, Fig. 1. Fig. 4is a transversesection through the valve and valve-controlling mechanism on the line Yof Fig. 1.

The tank A is of the usual or any suitable construction either for anelevated or low down tank and is provided at its bottom with a fittingB, connected with the flushing-pipe and formed at its upper end with aconcave valve-seat B, upon which seatsthe rubberincased flush-valve E.The fitting B is formed or provided with a branch I), to the upturnedend of which is connected the overflow-pipe D, which conveys theoverflow to the flush- 5'0 pipe below the valve E.

- F designates the valve-stem, secured to the center of the valve E andterminating at its upper end in a ring or loop, by which the valve andstem are suspended from the flushing-lever F G designates a horizontalbar having at one end a split ring G, which embraces the overflow-pipe Dand is provided with .lugs g g, through which pass a bolt 9 bywhich thebar G is securely attached to the overflow-pipe at any desired height.the valve and is formed with an opening g through which the valve-stempasses. At its rear end the bar G is widened and formed or provided withthree standards H H 11*, constituting supports for a pivotal pin h uponwhich are pivoted thevlevers I I. The space between the standards H H ison line with the valve-stein and receives the end of the lever I, whichextends toward the overflow-pipe Dand is formed or provided with acounterbalancing weight or head (1?. The lever I has a hole boredthrough it on a vertical line with the center of the flllSll-Vflh'e forthe passage of the valve-stem, such hole being sufficiently large toallow the valve-stem to slide freely therethrough, when by the elevationof the weighted end of the lever the hole is brought to a verticalposition, as shown in dotted lines in Fig. 1. The diameter of this hole,however, is such that when the weighted end of the lever I is lowered,as shown in full lines in Fig. 1, the metal at the ends of the holeforming sharp angles will catch and frictionally bind the stem andpreventit from moving.

The lever I is pivoted between the standards H H The short arm H of thelever I projects at a downward inclination toward the overflow-pipe andat one side of the lever I and is formed or provided with alaterallyprojecting toe 72. which passes under lever I between the valve-stem and the overflowpipe. The long arm H of the lever I projects in anopposite direction and terminates at its end in an enlargement bored forthe reception of the end of the float-rod K, to which is attached asmall float M. The float-rod is secured to the lover I by a set-screw'n, which allows of any desired adjustment.

An arm L, depending from the under side too I The bar G projects over ofthe lever 1, contacts with a stud m, projecting from the rear end of thebar G when the float is at its lowest required point and acts as a stopto prevent further descent of the float.

Operation: The tank being filled with water and the parts being in thepositions shown in full lines in Fig. 1, the valve maybe raised toproduce a flush by pulling down the outer end of the flushing-lever Fwhich will cause the valve-stem to slide upward without impediment. Whenso raised, the valve-stem will be held in position by frictional contactwith the angles at the end of the hole through the lover I, the leverremaining at the inclined position shown in full lines in Fig. 1 and thesides of the hole through which the stem passes being oblique to thestem. The counterweight on the end of the lever I is sufficient to bindthe lever at the angles formed with its upper and lower sides by thesides of the hole, so as to prevent the stem from slipping downward.When, however, the tank has been emptied and the float caused todescend, the latter will draw down the lever I at its outer end andraise the toe It, thus lifting lever I until the hole through which thevalve-stem passes becomes vertical and no longer binds the valve-stem,whereupon the latter being released will with its attached valve dropand the valve close the outlet to the flush-pipe. The tank may then befilled in the usual way.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In flushing apparatus, the combination with the flush-valve and itslifting-stem, of a gravitating bar or lever having an opening throughwhich said stem passes and in which it is frictionally held when thevalve is raised, a float, a lever to which said float is connectedhaving a projection adapted to engage with said gravitating bar orlever, whereby, on the descent of the float, the latter will be liftedand the valve-stem released, substantially as described.

2. In flushing apparatus, the combination with the flush-valve and itslifting-stem, of a gravitating or counterbalance bar or lever having ahole through which said stem passes and in which the latter isfrictionally restrained when the valve is lifted, a stationary bar towhich said lever is pivoted, a float, a lifting-lever to which saidfloat is connected having a toe or projection to engage with saidgravitating lever and lift the same when the float has descended to itslowest required limit, substantially as described.

3. In flushing apparatus, the combination with the flush-valve and itslifting-stem, an overflow-pipe and a horizontal bar secured thereto, ofa gravitating bar or lever attached to said horizontal bar and adaptedto frietionally restrain said valve-stem when raised to empty the tank,a float and a lever to which said float is connected, said lever beingpivoted on said horizontal bar and provided with a too or projectionwhich extends under said gravitating lever, whereby when said floatdescends, said gravitating lever will be lifted and the valve-stemreleased.

4:. In flushing apparatus, the combination with the flush-valve E,lifting-stem F, and overflow-pipe D, of the bar G, secured to the pipeD, and provided with standards II, II,

H weighted gravity-lever I, pivoted between two of said standards andformed with an opening through which said stem passes and with the edgesof which it engages and is held when lifted, lever I, pivoted betweentwo of said standards and provided with a toe or projection h passingunder lever I and float M, connected to lever I, the parts being soarranged that when the float descends the lever I will be lifted and thevalve-stem released.

In testimony whereof I affix my signature in presence of two witnesses.
